Gardner Dozois did two more big anthologies, "best of best" selections drawn from his first 20 Best of the Year anthologies done for Bluejay and then St. Martin's. (He did five earlier, shorter, best of the year volumes for Dutton, succeding Lester del Rey.) This first volume includes stories published from 1983 to 2002, and as you might expect, there are indeed some overlaps with this Modern Classics volumes published from 1992 to 1997, also by St. Martin's.
